un.onInst
I'm getting the following error in my script upon compile:

Function: "un.onInit"
Call must be used with function names starting with "un." in the uninstall section.
Usage: Call function_name | [:label_name]


The code that it's crashing on is below howver I'll just briefly explain what I'm doing. For both the installer and uninstaller I want it to call the function KillProgramExe to terminate the running program before its file is updated or so it can be delted upon uinstallation.

What is causing this bug?

Code below:

;**************************************************************************************************
;FUNCTION - ONINIT
;**************************************************************************************************

Function .onInit

;Check if the program exe is running before proceeding installation
Call KillProgramExe

SetOutPath $TEMP
File /oname=spltmp.bmp "Images\splash.bmp"

; optional
; File /oname=spltmp.wav "Data\splash.wav"

splash::show 1000 $TEMP\spltmp

Pop $0 ; $0 has '1' if the user closed the splash screen early,
; '0' if everything closed normal, and '-1' if some error occured.

Delete $TEMP\spltmp.bmp
; Delete $TEMP\spltmp.wav

FunctionEnd


;**************************************************************************************************
;FUNCTION - UN.ONINIT
;**************************************************************************************************

Function un.onInit

;Check if the program exe is running before proceeding uninstallation
Call KillProgramExe

FunctionEnd

;**************************************************************************************************
;FUNCTION - KillProgramExe
;**************************************************************************************************

Function KillProgramExe

FindProcDLL::FindProc "${MUI_PROGRAM_FILENAME}.exe"
StrCmp $R0 1 foundexe notfoundexe

foundexe:
KillProcDLL::KillProc "${MUI_PROGRAM_FILENAME}.exe"

notfoundexe:
;MessageBox MB_OK "Program is not running"

FunctionEnd

I mean I can get it to compile by duplicating the function KillProgramExe with adding a un. before its name but surely this isn't the way necessary.

Whats the point of havint two identical functions except for their name?

No need to check first if running, the trykill will just function if app is not running anyhow.

the point is, that functions without un. prefix won't be compiled into the uninstaller.exe and so will not be usable inside uninstaller.exe.
